Unknown content in Cards

I’ve spent the past 30 minutes trying to reliably replicate this issue but I can’t find anything consistent. I’m getting content in Cards simply saying Unknown (see bottom of screen shot):

This is the card and you’ll see there’s nothing below the Button component. It’s on a global but despite it being replicated in four places, it can appear in different places on different instances.

It’s completely intermittent, it can be there one minute, I click through a few things on the node browser, click back and it’s gone.

Can you send me the project, dan@realmacsoftware.com and I’ll take a look!

It won’t be any help (I think) as it’s not showing up now. I saved when it happened but on opening it was back to normal. It’s happened twice but I still can’t reproduce it reliably.

Okay, keep us posted. If it does happen again, do send over the project file so we can see if we can reproduce it (and fix it)!
